Simon, I'm sure you've contacted Inland Revenue on numerous occasions regarding your tax rebate and have been 'armed' with all the relevant information?
If you haven't already, I'd suggest writing directly (don't phone) to the Customer Services Manager at your particular tax office explaining the inefficient service you have received from them. These sort of letters SHOULD be taken very seriously if they wish to meet their Customer Service key performance indicator as part of their overall yearly production targets.
Sorry if you've already done all this, but all I know is if we received such a letter it WOULD be acted on immediately otherwise questions would be asked!
If not I'll ring them internally for you through the Govt. phone network, believe me it works
